* * cygerrno.h: New file. Use this throughout whenever errno manipulation isChristopher Faylor2000-08-221-0/+1
| | | | | | | | | | | | | | | required. * errno.cc: Use DWORD to hold Windows errors. (geterrno_from_win_error): New function. (seterrno_from_win_error): Use geterrno_from_win_error to convert supplied windows error (suggested by Corinna Vinschen). * path.cc (symlink_info): Add error element. * path.cc (path_conv::check): Remove errno setting. Use new symlink_info errno element to set path_conv error, where appropriate. (symlink_info::check): Set error element rather than attempting to manipulate errno. Add more checks for trailing / and /.. even though they are currently useless. Avoid setting EINVAL. * path.cc (normalize_posix_path): Correct check for trailing /.
* * winsup.h: Split out dtable definitions into separate header file.Christopher Faylor2000-08-121-1/+3
| | | | | | * dtable.h: New file. * sigproc.h: Eliminate pinfo.h usage here. Use it in source files that need it.

(select_stuff::wait): Just return success or failure and let caller fill in fd_set. * pinfo.h (pinfo): Eliminate self-referential pointer to sidbuf since pinfo structure exists at random locations now. * fork.cc (fork): Use 'use_psid' element to control when the psid is relevant. * shared.cc (sec_user): Ditto. * spawn.cc (spawn_guts): Ditto. * uinfo.cc (internal_getlogin): Ditto. * syscall.cc (seteuid): Ditto. Set use_psid element.
